I have a 48x40x12x Lite-on CDRW, and it is connected using a 40pin IDE cable. Will upgrading to an 80 IDE cable increase its performance, or is the writer still the limiting factor?
CD-RW's are ATA-33, and ATA-33 drives don't require 80 wire IDE cable for full performance. 40 wire cable is enough

40 wire for a single drive... 80 wire if there is another drive attached, just to reduce any possible bandwidth overload issues.

I just anwsered the exact same question from somone else less than a week ago. weird. an 80 pin IDE cable is meant for the ata100 or 133 standard and will make no difference on your optical drives because they are transmitting at ata66. however, rounded ata133 cables look really cool.
